Evaluating the Perimeter

You can tell a lot about a man by how loudly he knocks on reinforced tempered glass.

A frightened driver stranded in a blizzard taps with flat palms. A cop bangs with the meat of a fist, low and rhythmic. The heavy, three-beat rattle against the clinic's front door was neither. It was the flat, metallic rap of a brass-cased knuckle duster or the butt of a heavy automatic.

I grabbed Vaughn by the forearm before the headlight sweep caught his white lab coat.

His bicep was rock hard beneath the thin scrub fabric. He stiffened, but he did not pull away. I hauled him two steps backward into the deep shadow behind the reception desk.

"Down," I mouthed against the collar of his coat.

He crouched beside me behind the laminate counter. His breath smelled like stale black coffee and winter air. His right hand hovered near the heavy curved scalpel tucked into his back pocket, but as he dropped, he swept a six-inch stainless steel bone rasp off the lower treatment tray.

"Is this your brother?" he whispered.

"No," I whispered back, my lips inches from his ear. "Garrison drives a silver Silverado with a rusted tailgate. That engine is an eight-cylinder diesel with a loose alternator belt. It belongs to Cyrus Hess's ridge crew."

Outside, another knock rattled the frame.

"Hey!" a voice yelled through the storm seals. "Anyone inside? Radiator blew two miles back! We saw the generator light!"

The voice had a gravelly rasp in the upper register. A slight vocal fry on the vowels.

I knew that throat. I had spent forty-five minutes with it piped directly into my noise-canceling headphones before midnight. On the wire, that voice was Unit Four. He was the one who had reported the road spike puncture on Mile Marker 9. His partner on the comms called him Checho.

"Don't unlock the deadbolt," I murmured.

Vaughn glanced down at me. In the dim glow of the exit sign, his gray eyes were sharp and furious. "I wasn't planning on inviting them for coffee."

"He's lying about the radiator," I said. "A cracked block on a diesel that size makes a wet hiss under the manifold. That truck is idling clean. They're probing."

"What do they want?"

"They want to know if anyone ran here on foot. And they want to see if this building has working landlines."

Vaughn shifted his weight. His shoulder brushed against mine, solid and warm through my damp parka. For a man who looked like an exhausted academic with a surgeon's hands, he didn't panic. He just got colder.

"Stay under the counter," he said.

"Vaughn—"

"I run this clinic," he said flatly. "I'm allowed to be an asshole to strangers at two in the morning."

He stood up, rolling his shoulders back, and clicked on a single low-wattage desk lamp. The warm pool of light cast long, skeletal shadows across the waiting room chairs and left the back hallway in total blackness.

He walked to the double front doors without rushing. He didn't drop the bone rasp. He simply tucked it behind his thigh, out of line with the glass.

I crept forward on my knees, pressing my shoulder against the lower shelf of the check-in desk. Through the gap in the privacy partition, I had a clear angle on the vestibule.

Two men stood on the salted concrete stoop. Both wore heavy oilskin coats and dark knit beanies pulled low over their brows. The taller one had his hands jammed deep into his coat pockets. The shorter one—Checho—had a fresh scrape across his left cheekbone and pale, restless eyes.

Vaughn stopped six inches short of the inner glass. He did not smile. He didn't even raise a hand in greeting.

"We're closed," Vaughn said. His voice carried through the intercom speaker with all the charm of a rusted bear trap.

"Doc, come on," Checho called out, leaning toward the metal speaker grill. "Our heater core went out near the creek turnoff. My buddy's fingers are turning blue. Just let us stand in the entryway while we call a tow."

"The lines are down across the entire county," Vaughn said. "There are no tows. The pass is shut at the summit."

"You got a landline, don't you? A landline runs on copper."

"The pole by the highway snapped forty minutes ago," Vaughn lied without a hitch in his pulse. "I'm running on four gallons of generator fuel and an emergency surgical case on the table. Back your truck off my lot."

Checho didn't leave. He stepped closer, cupping his gloved hands around his eyes to peer through the frosted glass.

"We saw someone cutting across the lower meadow ten minutes ago," Checho said. "Looked like a girl in a dark snow jacket. Thought maybe she was heading this way for help."

My pulse hit my throat. I pulled my knees tighter against my chest, gripping the strap of my radio bag.

Vaughn didn't blink. He didn't look back toward the reception counter.

"I have two hundred pounds of aggressive livestock guardian dog bleeding out in my operating suite," Vaughn said, his voice dropping into a dry, menacing drawl. "If someone walked onto my property, they're either in the barn or they're frozen in the ditch. If you step off that porch toward the pens, you'll be dealing with two twelve-gauge rounds of rock salt. Get in your truck and drive back to town."

Checho stared through the glass for three long seconds.

The tall man behind him tapped Checho's elbow. He muttered something low in Spanish.

Vámonos. No hay nada aquí. El gringo está armado.

I caught every syllable. Let's go. There's nothing here. The gringo is armed.

Checho spat onto the snow-covered stoop. "Real neighborly, Doc."

"Have a safe drive," Vaughn said.

He stood perfectly still until both men turned, trudged down the steps, and climbed back into the idling diesel. The heavy engine revved, tires churning through the fresh four-inch powder as the truck swung around in the circular drive.

Vaughn let out a slow, measured breath. He clicked off the desk lamp, plunging the lobby back into darkness, and walked back behind the desk.

"You're very good at being unpleasant," I whispered from the floor.

"It's a gift," he said. He extended a hand down to me.

I looked at his long, calloused fingers. His knuckles were clean, scrubbed raw from surgical prep. I took his hand, and he hauled me up in one smooth motion. His grip was steady and surprisingly warm.

"Unit Four," I said, steadying my feet against the linoleum. "His name is Checho. He works the perimeter drops for Hess."

"They're looking for you," Vaughn said.

"They're looking for the audio file on this flash drive," I corrected. "And they're looking for Garrison. If they find Garrison first, they'll kill him. If they find me first, they'll make sure neither of us talks to the state police."

"The storm bought us until dawn," Vaughn said, glancing at the front window. "No one is driving heavy machinery up Black Ridge until the wind dies."

"Vaughn," I said, grabbing his sleeve again.

"What?"

"Look at the snow."

The truck was backing out near the western fence line. As it reversed, its dual high beams swept across the clinic's side yard, lighting up the deep drift beside the generator exhaust.

There, carved sharp and dark into the white crust, was a clean line of boot prints.

They started at the tree line. They led straight across the yard. And they ended directly at the clinic's rear airlock hatch.

The truck paused at the end of the driveway. The driver's side window rolled down two inches. An arm emerged, pointing a high-powered spotlight right at the fresh tracks.

The light held there for five agonizing seconds.

Then the spotlight clicked off. The truck didn't speed away. It rolled slowly into the tree line across the road and killed its headlights, sinking into the dark.

They hadn't left. They had set a watch.

Vaughn stared at the empty road, his jaw tightening.

"We have about an hour," he said softly.

"Less," I said. "They're waiting for backup."
